KOCH INDUSTRIES INC CHARLES G. KOCH Chairman and Chief Exacutive Officer June 5, l975 Mr. Roger L. MacBride Suite 42 240l Arlington Blvd. Charlottesville, Virginia, 22903 Dear Roger, I was delighted to learn that you are writing a popular book to introduce Libertarianism. Such a book should prove very effective in getting across the rudiments of our philosophy to a large number of people who would otherwise never be exposed. If distributed and pushed properly readership should be very large since interest will be high during the Presidential campaigns. The approach in the Introduction is just right, in my mind, for this type of book for this purpose. To have wide appeal the book needs to be written simply, directly and interestingly, as you are doing. Although Liz and I probably won't join you at the Convention, we send you our best wishes and total support. Keep up your good and vital work! with best regards, Sincerely, EXECUTIVE OFFICES.
